[0021]

Next, a super probe according to the present invention will be described.
A description will be given based on the embodiment or the modification shown in FIGS. Embodiment 1 The first embodiment proposes use as a probe. FIG. 1 or FIG. 2 shows a diagram of the probe in the first embodiment. It comprises a tip 1, a tip terminal attaching means 2, a grip tip coupling means 3, a grip 4, a tip attaching means 5, and a tip terminal 6.

The tip terminal 6 (the probe here) is a PMMA
(Polymethyl methacrylate) or polyimide resin, and the tip terminal 6 is detachably attached to the tip terminal means 2 by the tip attaching means 5, in this case, by a cutting force. Have been.
The distal end 1 is connected to the gripper 4 at a mono-angle with the gripper distal end connecting means 3. Here, the angle of the mono angle is set to 25 degrees. At this time, the tip 1, the tip terminal attaching means 2, the gripper tip connecting means 3,
The gripper 4 and the like were made of stainless steel. Of course, a material such as aluminum or brass may be used.

Here, the tip terminal (the probe in this case)
Is inserted into a groove such as a molar, and the probe is performed. The sensed tactile sensation is transmitted through the distal end portion 1, the gripping portion distal end connecting means 3, and the gripping portion 4, and is transmitted to the fingers. Then, the presence or absence of a lesion such as dental caries is determined at the probed site. At this time, in FIG. 1, the leading terminal may be inserted and used from below the tip 1 as shown in FIG. 2, or may be inserted and used from the top in the opposite direction. When used in this way, two angles can be selected, and the blind spot on the probed area can be almost eliminated. Here, this tip terminal attaching means 2 may be a cylinder or a double taper as shown in FIG. In the case of a double taper, the insertion feeling is very good. Further, the insertion feeling and the inset force may be controlled by making a cut as shown in FIG. These are examples of the easy-to-set means.

Although a detachable structure is adopted here,
An integrated structure may be used.

Here, the tip terminal may be in a form that cannot be separated from the grip portion. In that case, the grip portion and the tip terminal may be made of the same material or may be made of different materials. Furthermore, according to the gist of the present invention, any manufacturing method, shape, or property may be employed, such as integral molding or separate manufacturing.

[Effects of the Embodiment] The probe of this embodiment can perform a probe without damaging tissues such as teeth.

[Second Embodiment] A second embodiment discloses a hand instrument which emits an electromagnetic wave from a front terminal and uses it. First, an example using a probe is disclosed, and then an example using a resin-filled tip is shown. Here, the former used wavelength uses a broad visible light, and the latter uses a narrow blue wavelength. Also disclosed are examples of using other wavelengths such as tooth quality improvement, bacterial control, glucan degradation, tooth grinding, and the like.

In the second embodiment, there is no means after the beam splitter and the detecting means in FIG. 4, and it comprises an electromagnetic wave source 7, a waveguide 9, a holding portion 10, and a tip portion (front terminal) 11. The cross section of the gripper and the tip is circular, the tip of FIG. 4 is conical, and the tip of FIG. 5 is a cylinder with a dome shape or spherical shape, or a truncated cone with a dome or spherical tip treatment. Things.

Here, the electromagnetic wave source 7 is a light of visible light,
The waveguide 9 or the electromagnetic wave source 1 has a coupling means to the waveguide 9 made of a light-emitting body such as an LED or an LD. This coupling means may or may not be provided as long as electromagnetic waves such as light from the luminous body are transmitted to the waveguide 9. Here, a convex lens is used as the luminous body to form the coupling means. Then, the electromagnetic wave emitted from the light emitting body is guided to the waveguide 9. At this time, the waveguide 9 used an optical fiber.

Then, an electromagnetic wave is introduced from the waveguide 9 to the probe holding part 10. At this time, the grip portion 10 may be easily detachable by a coupler such as an optical connector, or may be fixed by bonding or the like. Then, the electromagnetic wave travels to the distal end portion 5 by repeating reflection in the holding portion 10 made of a transparent resin having a metal coating on the surface. Then, an electromagnetic wave (light) is emitted from the tip terminal 6, the distal end portion 1, or the grip portion 10.
This is the electromagnetic wave emission means.

Here, if a broad visible light is used as the electromagnetic wave source, the terminal becomes a shining tip such as a shining probe. If the light is blue light, it can be used as light for resin polymerization. In this case, the leading terminal may be used as a filling tip. This is convenient because the resin can be given a beam shape with a filling device and can be immediately cured by shining light.

At this time, 9.1 μm and 9.4 μm from the leading terminal.
Any one of electromagnetic waves at wavelengths such as m, 9.6 μm, and 100 to 300 nm, or a combination thereof may be emitted. In this case, the crystal alignment of the teeth can be performed.
Further, the combination here means 9.6 μm and around 200 nm, 9.4 μm and around 200 nm, 9.1 and 200 nm.
Around, 9.1 μm and 9.4 μm, 9.1 μm and 9.6 μ
m, 9.4 μm and 9.6 μm, 9.1 μm and 9.4 μm
And 9.6 μm. At this time, the critical pH of the tooth
Immediate and efficient etching can be achieved by applying the following liquids and irradiating them with electromagnetic waves, and can be modified by irradiating such liquids with a liquid having a critical pH or higher. If an infrared ray near 1038 cm-1 is used, caries bacteria suppression, glucan decomposition, dentin cutting, tartar removal, and the like can be performed. (Electromagnetic wave intensity generally tends to be higher in later ones.)

Specifically, an electromagnetic wave source such as a CO ₂ laser is used as the electromagnetic wave source 7 (in the case of the order of 9 μm), and a known infrared fiber is used as the waveguide 9. In the case of the ultraviolet region, various krypton lasers are used as the electromagnetic wave source,
Known visible or ultraviolet fibers are used for the waveguide 9. Further, for the grip portion 10 and the like, a material suitable for each band is selected from the materials described below. 9 μm as an example
If a table is used, polyethylene or germanium is used. Further, the grip portion 10 may adopt a two-layer structure of the inside and the outside as a fiber-like structure to further reduce the loss.

[Effects of the Embodiment] The examination of a closed tissue such as a dark oral cavity can be inspected by visualization. Further, it is convenient because the resin can be polymerized or an electromagnetic wave can be easily and reliably supplied to an action site such as a lesion. Further, if an electromagnetic wave such as a tooth modification is used, it is useful for improving a tooth in a site such as a fissure or an interdental space. In addition, it can control bacteria, decompose glucan, and grind, cut, and remove tartar.

[Third Embodiment] In the third embodiment, a function for diagnosing a tissue such as a periodontal tissue or a tooth contacting the front terminal by supplying an electromagnetic wave to the front terminal and detecting a reflected wave thereof. A hand instrument having the following is disclosed. Here, FIG. 4 discloses a conical tip terminal as the tip terminal, and FIGS.
Discloses a super probe having a tip terminal mainly used for periodontal tissue. 4 or 5, the electromagnetic wave source 7, the beam splitter 8, the waveguide 9, the holding portion 10, the tip portion (front terminal) 11, the detecting means 13, and the amplifier 14 are provided. Here, the electromagnetic wave emitted from the electromagnetic wave source 7 passes through the waveguide 9, the grip portion 10, and the distal end portion (tip terminal) 11, and is partially reflected at the distal end portion and partially emitted to an organization or the outside. You.
At this time, the reflection component returns to the holding unit 10, the waveguide 9, the beam splitter 8, and the detection unit. As a result, a change in the amount of electromagnetic waves absorbed (emitted) to the outside such as a tissue from the distal end is detected by the detection means.

In this embodiment, the cross section of the grip portion and the tip is circular, the tip of FIG. 4 is a conical probe, and the tip of FIG. 5 is a cylinder having a dome shape or a spherical shape, or a truncated cone. A probe with a dome or spherical tip. Here, the tip may have any shape such as a plane, concave, convex, sphere, or elliptical sphere as long as it reflects at least a little. FIG.
It is particularly suitable for teeth and the like, and FIG. 5 and the like are suitable for examination of periodontal pockets and the like. In the case of a tip terminal used for a periodontal pocket as shown in FIG. 5 or FIG.
Alternatively, as shown in FIG. 6, a reflective coating is applied to use the side surface, only the tip portion is used without coating only the tip portion, or both the tip portion and the side portion of the terminal are used. Yes, depending on the purpose of use. Here, the black part is the total reflection coat, the partial reflection coat or the like, and the white part is the non-coat part. At this time, the thickness and material of the coat may be any as long as they conform to the gist of the present invention. That is, any structure may be used as long as electromagnetic waves can be propagated inside the grip portion or the like, and interference or leakage of the internal electromagnetic waves with the outside can be reduced or eliminated. As an example, a metal coating or a metal-colored paint may be applied or plated, or a paint such as white, red, or black may be used, or a resin or other material having a different refractive index of a grip portion may be covered. good.

As an example, the tip terminal shown in FIG. 5 can inspect the absorption over the entire circumference, so that the sensitivity is high. In FIG. 6, 1 can be measured linearly at a fixed place such as along the inner epithelium or the side of the pocket. . 6 in FIG. 6 has an inflection point (line) or a threshold value for the insertion position (velocity) versus the measured value such that the output changes when the output exceeds a certain range, so that the distance is calibrated and confirmed on the inflection point (line). Can be. 3, 4, 5, 6 in FIG.
Means that the output increases and decreases nonlinearly, and in particular, 3 and 5
The conversion function has an inflection point (line) or a threshold value. In FIG. 6-3, since there is an inflection point near the tip, if this distance is about 2 mm ± 1 mm, the periodontal pockets of a healthy person and a sick person can be quickly separated and the pocket length can be measured. . In FIG. 6, since there is an inflection point in the gripping direction, overflow of measurement or the like can be detected.

6 in FIG. 6 can secure a large output even with a shallow pocket. 4 in FIG. 6 can measure a deep pocket with high accuracy. In FIG. 6, since only the tip has sensitivity, diagnostic information can be obtained regardless of the depth of the pocket. 6 in FIG. 6 can be detected over the entire circumference of the leading terminal and has high sensitivity. In this case, in particular, the sensitivity of the tip portion of the leading terminal tends to be high, and therefore, it is suitable for diagnosis. 5 and 6, the terminals 1, 2, 3, 4, 5, and 5 in FIG.
6 is more suitable for pocket depth measurement, and 7 and 8 in FIG. 6 are more suitable for diagnosis. FIG.
Has an intermediate character and is suitable for both depth and diagnosis, but it is up to the surgeon to finally decide which terminal is to be used for which purpose. Also, the area and shape of the reflection coat of the front terminal may be any shape or shape according to the gist of the present invention.
The area may be sufficient.

Here, in FIG. 4 or FIG. 5, the electromagnetic wave source 7 is made of a light emitting body composed of a visible light that outputs at least one wavelength, an LED, an LD, etc., and is guided to the waveguide 9 or the electromagnetic wave source. There is a coupling means to the wave path 9.
This coupling means may or may not be provided as long as electromagnetic waves such as light from the luminous body are transmitted to the waveguide 9. Here, a convex lens is used as the luminous body to form the coupling means.
Then, the electromagnetic wave emitted from the luminous body passes through the beam splitter 8 and is guided to the waveguide 9. At this time, the waveguide 9
Used optical fiber. Here, the beam splitter 8 uses a 50:50 cube type in FIG. 4 and a partially transmitting mirror (here, a half mirror) in FIG. 5. Anything along the line is acceptable.

Then, an electromagnetic wave is introduced from the waveguide 9 to the probe holding part 10. At this time, the holding portion 10 and the waveguide 9 may be easily detachable by a coupler such as an optical connector, or may be fixed by bonding or the like. Then, the electromagnetic wave to the distal end portion 11 proceeds by repeating reflection in the holding portion 10 made of transparent resin having a metal coating on the surface. These are electromagnetic wave supply means. The tip 11 also repeats internal reflection from the difference between the refractive index of air and the refractive index of resin, and finally returns to the waveguide 9. Then, the electromagnetic wave enters the beam splitter 8 from the waveguide side through the waveguide 9, and then a component that proceeds toward the detection unit 13 is generated, and the detection unit 13 returns to the electromagnetic wave (light) from the tip. Can be detected.

Here, the detector uses a photodiode, a phototransistor, a photomultiplier, or the like. The detecting means 13 uses an amplifying means 14 (gain | G |> 0) in accordance with an input level of a display device at the subsequent stage or an A / D converter. If the level adjustment is unnecessary, the amplifying means 14 is not needed. This output level indicates the degree of absorption of the object that has come into contact with the leading terminal.

Here, pocket measurement will be disclosed as a first example of use. This tip is inserted into the periodontal pocket. The periodontal pocket becomes deeper as the periodontal disease progresses. When the disease progresses, for example, it becomes acute, secretions such as bleeding and drainage occur.

First, an example in which the present invention is used to measure the depth of the former pocket will be disclosed. Here, the tip terminal may have a normal so-called probe shape, but it is better to adopt a round probe shape whose tip does not damage the pocket. When the leading terminal having the above mechanism is inserted into the periodontal pocket, the absorption increases by the degree of insertion. The degree of this absorption is defined as the depth of the pocket. Specifically, a calibration curve or a function formula of depth versus absorption is previously obtained in an aqueous solution or the like, and the inspection is performed based on the calibration curve or function formula. More specifically, a conversion means comprising a calibration curve or a function formula is stored in the computer, and the depth with respect to the degree of absorption is displayed on a display device or the like. Here, the pocket depth error due to the difference in the substance in the pocket may be corrected based on the next component inspection function in the pocket. In this case, the electromagnetic wave used may be any wavelength such as ultraviolet, visible, and infrared. In particular, H ₂ O near 3300 cm −1 or 1600 cm −1 may be used. When the electromagnetic wave is in the infrared region, a CO ₂ laser, a semiconductor laser, or a glow bar light source may be used, but a laser is convenient. Here, when a multi-wavelength light source such as a lamp is used as the electromagnetic wave source, when a specific two or more wavelengths are used, or when a specific single wavelength is used, the coherence is further increased.
There are a case where lent light is used, a case where non-coherent light is used, and a case where a combination thereof is used. For example, when the detected intensity difference between two adjacent wavelengths is taken as the absorption intensity, a pocket measurement suitable for disturbance can be performed. If a multi-wavelength light source such as a lamp is used, errors due to absorption intensity at each wavelength can be easily averaged, and disturbance can be averaged to measure pocket depth. When at least one or more specific wavelengths are used, it is suitable for diagnosis to be described later. In the case of coherent light, there is a case where it is easy to make a single wavelength, an optical circuit is easily formed, and it is suitable for diagnosis. In addition, since the light intensity distribution inside the front terminal can be easily calculated, it is also suitable for pocket measurement. Non-coherent light is suitable for pocket measurement since the leading terminal light distribution is easily averaged, and can be used for diagnosis as described later. Further, an inflection point may be provided by reducing the pocket measurement error by making the leading terminal light distribution uniform with a plurality of wavelengths, or increasing or decreasing the electromagnetic wave intensity only at a specific portion.

Next, the function of examining the components in the pocket will be disclosed.
If periodontal disease progresses, bleeding or drainage occurs,
The component inside the periodontal pocket during healing may be approximated to almost water only, depending on the problem of detection sensitivity.
(Of course, it may be stricter, or the absorption intensity may be corrected when measuring along the gingiva.) The point is that it is only necessary to be able to distinguish the pathological state from the relatively healthy state, so that only water and blood, plasma It suffices if differences between the components, bacterial components, and inflammatory substances (such as enzymes) are determined.

As an example, two wavelengths of H ₂ O near 3300 cm −1 or 1600 cm −1 and both 660 nm and 940 nm of hemoglobin or both of them are adopted as electromagnetic wave sources. The difference is the degree of bleeding. Here, any index may be selected according to the gist of the present invention, such as blood, plasma components, bacterial components, inflammatory substances (eg, enzymes), etc., and may be used for any diagnosis. . As an example, a wavelength per 1 μm is used as an index of blood. Further, when two wavelengths of 660 nm and 940 nm are used,
The oxygen saturation may be measured based on the ratio of the two wavelengths.
Specifically, a known oxygen saturation measurement function is installed in a conversion circuit such as a computer, and the 660 nm and 94 nm of the present invention are measured.
The oxygen saturation can be detected by converting the detection outputs at two wavelengths of 0 nm by a conversion circuit and displaying the converted output on a display device or the like. In addition, background detection of this detection output may be performed. If this is done in any case, the accuracy is improved.
A pulse wave may be obtained by changing either or both of the two wavelengths.

As another example, an examination of dental caries is disclosed. Here, the tip terminal is connected to the object to be measured 12 (here, tooth).
The electromagnetic wave is absorbed by the object at the interface between the object and the probe and the internal reflection component is reduced. Specifically, the absorbance when a probe is applied to a healthy tooth 12 and the absorbance when applied to an object such as a carious tooth 12 differ.

With healthy teeth, it does not stick. That is, since the contact area is small and only the hard structure such as the apatite crystal is used, the electromagnetic wave is not easily absorbed from the leading terminal. (Selecting a specific wavelength further reduces the absorption.)

In addition, a diseased tooth sticking tooth, that is, a tooth having a stick fisher, has a large contact area, and has a large amount of organic components other than apatite due to tissue destruction, ie, H ₂ O, CH, CO, and the like. Therefore, the absorption from the leading terminal shows different absorption between the morbid state and the health state. Here, when a wavelength other than the apatite absorption wavelength is selected, the absorption at the diseased site increases. The electromagnetic wave source used was visible light, but infrared light of H ₂ O was 3300 cm.
-1 or 1600cm-1, near CH etc.
A wavelength around a little less than cm-1 or around 1400 cm-1 may be used, or the sensitivity may be raised by using around 1,000 cm-1 of CO.

Furthermore, 1038c specific to α13 binding
A wavelength near m-1, 1034 cm-1 may be used. In this case, the caries risk at the examination site is determined. At this time, the moisture of the plaque may be measured at the above-mentioned wavelength, and the measurement wavelength may be corrected by the correction means to reduce the CO absorption wavelength measurement error. Of course, the vicinity of 1016 cm-1 of α16 glucan and the vicinity of 1055 cm-1 of fructan may be similarly used. Here, H ₂ O around 3300 cm −1 or 160
Nearly 0 cm -1 or possibly 1080 cm of the phosphate related substance in the polysaccharide peak group
By using a peak such as −1 as an internal standard, the peak intensity of glucan or fructan may be compared to indicate the caries risk.

Here, the wavelength of the electromagnetic wave supplied, for example, from 8.8 μm to 10.4 μm or 1
When the wavelength is set from 00 nm to slightly less than 300 nm, absorption at a diseased site becomes smaller than that at a healthy site. In this manner, any wavelength may be used as long as the wavelength that changes before (healthy part) and after destruction (pathological part) of the index organization is selected.
A pathological tissue such as an abscess or a tumor may be detected with a difference in electromagnetic wave absorption characteristics from a healthy tissue. Here, when such infrared light is used, a CO ₂ laser or a glow-bar light source is used as an electromagnetic wave source.

Although a continuous wave is used, a pulse wave may be used. In this case, the re-radiated wave may be observed, or the fluorescence of the tissue may be observed during the rest period of the pulse. Further, a plurality of diagnoses may be performed simultaneously by using the above various wavelengths in combination. As an example, using a wavelength of H ₂ O, CH or PO ₄ , an effect determination after cleaning is performed on a tooth fissure that can be determined to be a sealant or a restoration. Specifically, the fissures are cleaned with a Robinson brush and dried with air. After that, H ₂
Inspection is performed using O, CH and PO ₄ wavelengths. At this time H
_{If a} large amount of ₂ O or CH is present, or if there is only a small amount of PO ₄ , repair is performed instead of a sealant.

[Effects of Embodiment] The depth of the periodontal pocket, which has been conventionally measured with a gauge, can be measured, and the progress of the disease state can be determined. In addition, it is possible to diagnose early occlusal caries, smooth caries, and the like that are difficult to understand using visual recognition or X-ray images. It can be used to diagnose components of body fluids such as saliva, blood, or gingival sulcus. In addition, the amount of oxygen supply such as periodontal tissue can be known, and the risk of periodontal disease can be determined. Diagnosis of lesions including abscesses and tumors is possible.

Any of S, alumina, zirconia, titania, various ceramics (these are functional because they easily transmit a specific electromagnetic wave), or any combination thereof may be employed. Of course, you may use as a material of another part. Here, these materials may be solid, gas or liquid. At this time, when a gas or a liquid is used, its surroundings may be coated with a solid, or a fluid may be used as the first terminal. Specifically, electromagnetic waves (light rays) are conveyed to the gas components generated by the air blower,
For example, a liquid such as water is ejected by an ejecting means, and an electromagnetic wave is carried in the flow to be used. In this case, since the operation of cleaning and drying the periodontal pocket and the propagation of the electromagnetic wave can be performed, the electromagnetic wave (light ray) penetrates deeply. These functions may be used for a known water pick or three-way syringe. Also, it may be used for parts other than the terminal.

Here, in the case of a polymer such as a resin, high performance by the addition of a functional group, copolymerization, bridge polymerization, block polymerization, graft polymerization, polymer blend, intermolecular crosslinking, single crystallization, polymer Higher-performance materials may be adopted by alloying, glass fiber reinforcement, filler addition, or compounding at all levels from the atomic level to the material level. For example, calcium carbonate, talc, glass beads, aluminum hydroxide, magnesium hydroxide, diatomaceous earth, silica, clay, clay, kaolin, barium sulfate, titanium oxide, carbon black, metal powder, graphite, shirasu balloon, potassium titanate, wax Fillers or auxiliary materials such as lastonite, carbon fiber, mica, glass, and asbestos may be added.

In some cases, the leading terminal may be made of porcelain, ceramics, ferrite, magnetic material, metal, organic compound, or the like. Further, the material of the terminal may be a hybrid structure, a polymer alloy, or a single structure having a single composition.

In the above-mentioned embodiment, the tip terminal attaching means and the tip end attaching means are formed by the incision force. However, any method such as screw, screw, groove, key and key way, various chuck structures, one-touch lock, etc. Means may be used. Alternatively, a detachable auxiliary device such as a chuck remover may be employed. As an example, a simple column or a double taper structure as shown in FIG. The grip portion may have a grip shape, or may be provided with a non-slip or the like by an elastic body, or provided with a groove or a bulge for appropriately fixing the finger, and any shape and properties along the finger of the present invention. But it is good. When passing electromagnetic waves,
A material suitable for the wavelength may be selected. As an example, a metal cavity or a cavity in which gas, liquid or solid is inserted may be used. This may be used for the leading terminal or the waveguide. More specifically, a metal pipe such as iron or stainless steel is used for the holding portion, and a waveguide is connected to one end of the holding portion,
Then, an electromagnetic wave (light beam) or the like is propagated through the inside to supply the electromagnetic wave to the leading terminal. Here, a liquid such as water or oil may be added thereto. Here, similarly, the leading terminal may be formed of liquid or gas.

The distal end may be directly or indirectly attached to any part of the gripping part, for example, by omitting the gripping part distal end connecting means. Further, the number of the distal end portions and the number of the gripping portions may be plural, for example, the distal end portions are attached to both sides of the gripping portion.

In the above-described embodiment, the gripper tip connecting means is a mono-angle, but may be a bi-bend or more bi-bend. The angle may be any angle such as 0 to 360 degrees. Also, a structure may be adopted in which the angle of the gripper tip connecting means is continuously changed by a screw or the like. The cross section of the grip portion and the tip portion may be any shape such as a circle, an ellipse, and a polygon. Further, the material of the distal end portion 1, the tip terminal attaching means 2, the gripping portion distal end connecting means 3, and the gripping portion 4 may be any material such as metal, resin, and porcelain.

As examples of these, the drawings of the patterns for various dental diagnosis treatment prevention shown in FIGS. 8 to 13 are disclosed. This is the description of the article related to the design if expressed in conformity with the design. Tip at the tip hole, root planing tip, tooth cleaning tip, crown polishing tip, pocket probe, various filling tips, various vanishers, various carvers , Various mirrors, various spatula, various brushes, various water picks, various air blowers, electric pulp diagnostic chips, electromagnetic wave supply chips, applicators and other dental treatment and preventive instruments (tip terminals) are used. Description of the Design The head part that is not blackened is the part that is to be registered as a partial design. The tip hole has a probe, root planing tip, tooth cleaning tip, crown polishing tip, pocket probe, various filling tips, various vanishers, various carvers, various mirrors, various spatula, various brushes, various water picks, various air Dental treatments such as a blower, electric pulp diagnostic chip, electromagnetic wave supply chip, applicator and other dental treatment and preventive instruments (tip terminals) can be used for one and many purposes, and the tip hole can be used from either side. A variety of angles can be selected to eliminate blind spots in the oral cavity. Further, a head portion having a front end hole for attachment may be provided on both the flat surface and the bottom surface. In this case, two types of front terminals can be easily used. Furthermore, the terminal may be disposable. This is very hygienic. Alternatively, the leading terminal may be made of resin or the like. In this case, the teeth are not damaged. Here, this product may be made of any material, but it is better to be made of a material that can be used in an autoclave. Has a common personality.

In the above-described embodiment, the tip terminal such as a sharp needle as shown in FIG. 4, the one having a dome shape or a spherical shape as a cylinder as shown in FIG. Although the probe is disclosed, the probe may have any shape as long as it can be used with the probe. Here, depending on the shape of the tip or the properties of the waveguide, the electromagnetic wave density may increase in a specific portion. Therefore, the electromagnetic wave density may be corrected or the shape may be set so as to be used in reverse. For example, if a laser is used as a light source, a polarization maintaining fiber is used as a waveguide, and a concave mirror curve is used as a terminal, the reflected beam density can be increased at a specific portion. If this part is a part without a reflection coat, favorable diagnosis can be made. Conversely, such a portion may be masked with a reflective coat, or uniform absorption may be obtained as a dispersed electromagnetic wave path. Here, depending on the object to be measured and the terminal used,
Conversely, the degree of reflection from the tissue may be detected by the detecting means. As a specific example, the level at the time of insertion is compared with the level at the time of insertion, using the detection level when held in the air as a reference value. When held in the air at this time, electromagnetic waves are emitted from the leading terminal and there is no reflected electromagnetic wave from the surroundings. Next, if the device is inserted into a tissue having a highly reflective metal crown or implant, reflected electromagnetic waves from the tissue may be generated.

As shown in FIG. 1, FIG. 2, FIG. 8 to FIG. 13 and the like, the tip can be replaced by a root planing tip, a tooth cleaning tip, a crown polishing tip, a pocket probe, various kinds of filling instead of a probe. Tip, various vanisher, various carver, various mirror, various spatula, various brushes, various water picks, various air blowers, electric pulp diagnostic chip, electromagnetic wave supply chip, one of the instruments for dental treatment and prevention such as applicator, or Whether the combination is used as the first terminal is not particularly limited at the discretion of the operator or the manufacturer. In this case, the attachment of the front terminals has a shape according to the modified example of the embodiment of the present invention, and is attached to the front terminal attaching means by the same operation. If these tip terminals are attached, various diagnoses, treatments and preventions can be performed. In addition, the terminal can be easily discarded, so that it is very clean to prevent hospital infection. Further, if the gripper and the gripper tip connecting means are made of an autoclavable material such as stainless steel or engineering plastic, it is even cleaner. Various tip chips as shown in FIG. 3 may be employed as an example of the terminal.

A tip with a blade may be used as a probe with a blade. As an example, a blade is attached to the tip of the probe as shown in FIGS. The blade is classified into a parallel blade type, an orthogonal blade type, and an intermediate blade type in between the parallel blade type and the orthogonal blade type according to the mounting position and direction of the blade with respect to the gripping portion. If this is expressed in conformity with the design, the description of the article related to the design
A very small blade is attached to the tip of the very fine shank tip. Description of the Design The head part that is not blackened is the part that is to be registered as a partial design. The incision of the periodontal ligament with a # 12 scalpel,
The blade is large and easily damages the surrounding tissue, and the incision by the probe was due to crushing, but by installing a micro blade or micro blade at the tip of the micro shank for cutting the periodontal ligament. The ligament existing in the deep part of the periodontal pocket also damages the surrounding tissue and can be easily cut sharply. Furthermore, it is classified into a parallel blade type which is easy to use especially for the buccal tongue and can be used all around, an orthogonal blade type which is particularly easy to use for mesio-distal, and an intermediate blade type having an intermediate property. Further, a micro blade having an orthogonal type is also suitable for simple route planing, which can be easily applied only to the work site without damaging the surrounding tissue, thereby enabling a stress-free medical treatment. Here, the blade may be sharpened so as to be freely applicable to various uses. That is, by making the blade sharp, gingival incision, pocket curettage, root bifurcation curettage, abscess incision, curettage near the gingival wall of the cavity wall,
Or ligament resection can be performed, and the blade is slightly rounded, which is suitable for various purposes such as plaque control of roots and crown surfaces. Alternatively, the leading terminal may be made of resin or the like. In this case, the teeth are not damaged. Here, this product
Although it may be made of any material, it is better to be made of a material that can be used in an autoclave. And so on.

The irradiated or supplied electromagnetic wave may be polarized such as linearly polarized light, circularly polarized light, or elliptically polarized light. Moreover, you may employ | adopt for a detector. With these, the nature and depth of the examination organization can be controlled, and the effects of stray light and the like can be suppressed. Further, a polarizing beam splitter or a wave plate may be used together therewith. In this case, the return electromagnetic wave can be efficiently captured by the detecting means, the absorption at the leading terminal can be efficiently performed, and the polarization change of the object to be measured can be captured. As shown in the optical circuit example of FIG. 16, a lens or the like may be provided in front of the detector to increase the sensitivity. In this case, the surface to be observed may be set anywhere from the surface (end face) where the electromagnetic wave such as the waveguide or the front terminal enters from the electromagnetic wave source to the front end of the front terminal. It may be set anywhere between large and small. At this time, the incident surface of the electromagnetic wave may be inclined to reduce stray light. As another high-sensitivity optical path example, an electromagnetic wave source is linearly polarized light, and a polarization beam splitter is used as a beam splitter. In this case, stray light from a surface (end face) where an electromagnetic wave such as a waveguide to the detector or a front terminal enters from an electromagnetic wave source is reduced, and sensitivity and stability can be improved. In addition, if a phase conjugate wave is generated as another circuit and injected into the front terminal, and the detector is set at the same optical distance as the point of generation, stable and highly sensitive measurement without disturbance (absorption intensity measurement at the front terminal) ) Can be. Further, as another circuit, only the center of the beam splitter may be transmitted, and the periphery may be coated with reflection to reduce stray light. Alternatively, the injection terminal and the reflection wavelength may be processed at different wavelengths by using the tip terminal as a principal wave generating crystal such as a harmonic wave crystal. In this case, the propagation of stray light to the detection system is reduced.

In the above embodiment, a metal coating (reflection coating) is applied to the grip portion. However, the range may be any, and the coating material and its electromagnetic wave properties may be changed as needed. For example, aluminum, gold,
For example, silver, chromium, MgF ₂ , and a dielectric multilayer film are coated or plated. Although loss is large, an inexpensive coat such as enamel or lacquer paint may be applied. In that case, a color having a high reflectance may be used according to the wavelength used. Further, the reflection coating and the non-coating portion of the above-mentioned terminal of FIGS. 4, 5 and 6 may be reversed.

Frequency modulation, amplitude modulation, phase modulation, 1 / f
Fluctuations may be used.

The wavelength of the electromagnetic wave emitted by the electromagnetic wave emitting means may be any wavelength, such as visible, ultraviolet, infrared, or radio waves. Wavelengths may be used. The irradiation port may be provided anywhere, and the introduction path may be any as long as the gist of the present invention is adopted. Here, the waveguide 9
May be a fiber-like object or a mirror-like object. When a waveguide is used, it may be used in accordance with the wavelength of the electromagnetic wave source. For example, the infrared band uses fibers such as silver halide, and the visible or ultraviolet band uses fibers such as plastic or quartz. The waveguide may be a wavefront-conserving type or a non-conserving type, and may be selected in consideration of the purpose of use, price, sensitivity, and the like. Similarly, a phase conjugate type may be adopted. The coupling means to the waveguide, the coupler to the gripper, and the like may be any as long as electromagnetic waves propagate.
Here, the end face may be parallel, concave, convex, oblique, or any other suitable object. Further, at the time of coupling, a light transmitting medium such as a gel may be used for the coupler or coupling means. Here, in the embodiment, the waveguide is used as the electromagnetic wave source. However, the electromagnetic wave source may be built in the holding portion without using the waveguide. Conversely, the structure of the waveguide 9 is changed to a gripper 10 or a terminal (tip) 11.
May be adopted. That is, the grip 10 and the tip terminal (tip)
11 may be a waveguide structure such as an optical fiber, and may be a structure in which only a reflection coating is applied to a tip portion thereof. In this case, when the grip portion is coated, coated, or covered, the error is reduced.

The power supply may be a battery, a commercial power supply, a built-in power supply, or an external power supply. The switch may be any switch. As an example, a slide switch or a push switch may be used for the grip portion, a foot switch, a switch by sign language input, or the like may be used. The tooth type (part) is displayed on the computer screen, and the inspection part and the tooth type (part) on the screen are displayed.
In addition, pocket depth, dental caries (C1 to C4), bleeding, and drainage may be correlated and examined. As an example, as shown in FIG. 17, an electromagnetic wave source and a detecting means are built in the gripping portion. At this time, the waveguide may or may not be used. Further, the sensitivity of the detector can be easily increased without using a lens or the like.

As a means for irradiating an electromagnetic wave to a tissue such as a tooth, a laser light generator may be used as an example above, or other means may be used as long as the electromagnetic wave can be irradiated. Specifically, laser light, natural light, medium waves such as radio waves, microwaves, X-rays, and sound waves, and any waves such as ultraviolet light, infrared light, and visible light may be used. Also, it may be a coherent wave or not a coherent wave. Here, the laser is NdYg, CO ₂ , He-
Ne, various types of yag lasers, various types of xenon lasers, various types of argon lasers, excimer lasers, dye lasers, semiconductor lasers, and the like may be used in any oscillation mode. Of course, a wavelength tunable laser using a grating, a double crystal, or the like may be used. Of course, the line width may or may not be used for various light sources.

When the electromagnetic wave is a radio wave, an antenna, a waveguide, an electromagnetic field lens or the like may be used. The infrared light may be received by an antenna. As the light source, any electromagnetic wave source may be used as long as it is suitable for the present invention, such as a global light source, a lamp, and an LED. For example, in ultraviolet light,
An ultraviolet lamp, a KrCl laser, a KrF laser, or the like may be used.

Here, an example using radio waves will be disclosed. That is, radio waves may be used to measure the depth of the pocket. In this case, the above mechanism differs from the light wavelength band. Specifically, in this case, one or both of the tip terminal and the grip portion are made of an electromagnetic wave propagating material (eg, ferrite or metal), and the waveguide is connected to the waveguide via a (electromagnetic wave) coupling means such as a coil. 9 is formed by a copper wire or the like. More specifically, a coil having a diameter of about 10 mm, which is about two turns, is prepared, and is installed so as to be wound around the holding portion. This high-frequency circuit is one side of the high-frequency bridge. Then, by detecting an energy change such as a current or frequency change of the bridge circuit, the degree of absorption of the electromagnetic wave into the tissue is determined. Of course, the degree of electromagnetic wave absorption may be measured by measuring the re-radiated wave without using a bridge circuit, or by taking the energy fluctuation of the circuit for supplying the electromagnetic wave into the degree of absorption. For the propagation of the high-frequency energy to the front terminal, any means may be used according to the gist of the present invention, such as by directly coupling and supplying the high-frequency energy from the high-frequency generation means (electromagnetic wave source). Further, the drive frequency used was about 200 MHz, but this frequency may be any value within the spirit of the present invention. As another method of using radio waves, a carrier wave may be an optical band and a modulated wave may be a radio wave. In this case, for example, a known optical modulation element may be inserted after the electromagnetic wave source. At this time, detection using the reference wave by the detector or detection not using the reference wave may be performed. When a reference wave is used, heterodyne detection or homodyne detection may be used.

As a result, the depth of the pocket is determined by the magnitude of the degree of electromagnetic wave absorption from the terminal to the tissue. (If the energy absorption is large, the depth of the pocket is large.) Also in this case, the conversion function between water and absorption intensity is measured in advance, a conversion means is prepared by a computer or the like, and the output of the present invention is input and displayed. It would be a pocket depth meter. In this case, the leading terminal may not need to touch the measurement organization in some cases.

Optical elements such as lenses and mirrors may be used to adjust the energy and range of the site of excitation by the irradiation electromagnetic waves.

At least one or more pulsed electromagnetic waves may be applied to teeth at appropriate intervals, or may be continuous waves. Further, the reflected or transmitted electromagnetic wave from the first pulse or the second pulse may be observed, or the phase matching may be adjusted by changing the interval between the first pulse and the second pulse. Also, the re-radiation may be viewed with one pulse, or the re-radiation with each pulse may be compared. The condition of the maximum re-radiated wave may be set in the irradiation means.

The wavelength of the irradiated electromagnetic wave may be a single wavelength or a plurality of wavelengths. Further, the electromagnetic wave used for the interference may be a plurality of interferences in many directions, a multiplex interference in which a plurality of interference waves are overlapped, or a combination thereof.
In this case, it is possible to irradiate a complex tissue with detailed irradiation for each part. The wavelength before the wavelength change may be used for excitation. The waves may be Fourier-combined.
In addition, any of linearly polarized light, circularly polarized light and random polarized light may be changed by a polarizer according to the irradiation purpose, depth, and the like.

The detection means is HgCdTe, CCD, InA
₂ , Pb ₂ nTe, Pb ₂ , Cd ₂ , Cd ₂ e, Pz
T, LiTaO ₃ , thermopile, bolometer, etc. may be used, and stray light may be removed by using an imaging means, a band-pass filter, a polarizing filter, a high-cut filter, a low-cut filter, or a specific range. Electromagnetic waves of (property) may be extracted. A similar effect may be obtained by applying an antenna or the like. Further, it may be used to adjust the detection sensitivity by adjusting and feeding back the signal intensity and wavelength of the electromagnetic wave to an optimum state, or to raise the diagnostic accuracy of the tissue. Here, a circuit for removing background light such as an indoor light may be employed.

In many cases, the resonance wavelength shifts as the crystal matching of the tooth apatite progresses. In this case, the excitation wavelength may be shifted and followed by the electromagnetic wave control means in accordance with the shift of the resonance wavelength. In addition, a pulse may be applied twice for a pulse pair or group, or a pair or group that excites three or more times may be used. In the case of a pulse, the electromagnetic wave control means may be scanned so as to obtain a pulse interval and a pulse wavelength that maximize the re-radiated wave.

Further, an infrared light source (global light source, CO ₂ laser light source, etc.) is provided at the end opposite to the irradiation end of the waveguide 9, and the light of the light source is passed through a filter or a diffraction grating to a predetermined wavelength. A certain wavelength, such as 9.6 μm,
The light may be guided to the waveguide 9 and irradiated. Further, the following wavelength may be applied. As an example, 8.8 μm to 10.0 μm of enamel (especially 9.1 μm, 9.4 μm, 9.5 μm, 9.6 μm, 9.7 μm,

It may be excited by an F laser. ) Is just one example. These may be used alone or in combination. Further, the reference vibration may be used, or harmonics may be used. Furthermore, cutting and tissue induction (including use as a reactor or the like) may be performed using these wavelengths. As an example, a tooth is cut by irradiation of a 9.6 μm electromagnetic wave. In this case 1
It is a great feature that the thermal influence on the pulp is small compared to other wavelengths such as a wavelength of 0.6 μm, and the cut surface is good.
As an example, the tip terminal may be a scaler or curette type tip terminal, and an electromagnetic wave of 9.6 μm or the like may be emitted from the cutting edge to perform tooth cutting, tartar removal, or curettage.
